Definitions

  • the present invention relates to a method for increasing the pressure drop in the gas turbine of a power generation system as a result of the preamble of claim 1.
  • a power plant has become known from document FR-358 569, in which an injector can be seen which is operated by compressed air and a gaseous fuel.
  • the task of this injector is to give the fuel / air mixture a higher speed before it flows into the combustion chamber of the power plant.
  • a steam is generated in this combustion chamber, which is detached from the injector and admixed with the mixture mentioned to increase the pressure.
  • the operation of a driving nozzle of an injector arranged in front of the combustion chamber can only be accomplished by a medium of high pressure.
  • a power plant with a conventional steam generator is not able to provide a quantity of steam with the necessary pressure. So if the amount of steam required to operate such an injector has to be specially generated, it is obvious that such provision triggers a reduction in the efficiency of the system.
  • the object of the invention is to maximize the efficiency in a method of the type mentioned at the outset by increasing the pressure gradient in the gas turbine caused by the compressor.
  • the main advantage of the invention can be seen in the fact that the pressure increase of the working gas in the gas turbine of a power plant system occurs without using the shaft power of the system. Wherever there is a post-compression stage to the existing compressor niche considerations, the yield from the gas turbine caused by the task solution according to the invention is several times higher than this power consumed from the additional compression.
  • Another advantage of the invention can be seen in the fact that the increase in efficiency is achieved both in pure gas turbine groups and in combination systems; furthermore regardless of whether the respective circuit has a constant pressure combustion chamber or an isochor combustion chamber.
  • the gas turbine group as an autonomous unit consists of a generator 1, a compressor 2, a combustion chamber 6 and a gas turbine 8.
  • the air 3 that is sucked in is compressed in the compressor 2 in the sense of a pre-compression and then reaches the injector 5 via line 4. namely through its catch nozzle; the injector 5 is placed upstream of the combustion chamber 6.
  • the air then thermally processed in this combustion chamber 6 acts as hot gas 7 on the gas turbine 8.
  • the gas turbine exhaust gases 9 are fed to the heat recovery steam generator 13, where they are used for energy purposes.
  • a high-pressure steam 10 is generated in a high-pressure steam generating part 14, which acts on the injector 5 via its driving nozzle. Since it is a two-pressure heat recovery steam generator 13, a low-pressure steam 11 is generated in a further low-pressure steam generating part 16. A part of this steam 11a is fed to the combustion chamber 6, and there, for example, reduces the NOx emissions. Another part of the low-pressure steam 12 acts as a coolant for the gas turbine 8. The cooled exhaust gases are then blown out into the open as flue gases 18 via a chimney.
  • a first feed water pump 17 provides the medium replenishment in the heat recovery steam generator 13, while a second Feed water pump 15 provides the promotion of the medium between the low-pressure and high-pressure steam generating part.
  • a circuit here that is designed such that the high-pressure steam 10 generated in the waste heat steam generator 13 acts on the driving nozzle of the injector 13 and causes the pre-compressed air 4 coming from the compressor 2, which flows into the injector 5 via the collecting nozzle, to further compress is before both media 4 and 10 flow into the combustion chamber 6 placed downstream of the injector 5.
  • the gas turbine 8 experiences a greater pressure drop than could only be built up by means of the compressor 2 alone.
  • this circuit according to FIG. 1 can be designed as a combination system, in that a steam part from the waste heat steam generator 13 would act on a steam turbine connected downstream of it and not visible. Such an arrangement can in connection with an additional firing in the exhaust pipe 9, at the latest in the heat recovery steam generator 13 may be advantageous.
